I'm trying to update an old Dell from 2007 and the motherboard says my current slot where I have an NVidia 9800GT is PCIE 2.0 x16. Most of the new cards on the market are PCIE 2, but I wasn't really sure what that x16 means and whether the newer cards would fit. Do I have to look for a graphics card that's specific to PCI 2.0 x16?
